AT88SA10HS集成電路（IC）的專用IC規(guī)格書PDF中文資料

Introduction

The Atmel CryptoAuthentication? family of chips is the first cost-effective authentication devices to implement the SHA-256 hash algorithm, which is part of the latest set of recommended algorithms by the US Government. The 256-bit key space renders any exhaustive attacks impossible.

The AT88SA10HS host version of CryptoAuthentication chips is capable of validating the response coming from the SHA-256 engine within an authentic CryptoAuthentication client (SA100S or SA102S), even if that response includes within the computation the serial number of the client. For detailed information on the cryptographic protocols, algorithm test values and usage models. See “Atmel AT88SA100S” and “Atmel AT88SA102S” datasheets, along with the application notes dedicated to this product family.
